This invention -relates to improvements 13 for the engagement oftheflange 14C of a in the construction of a valve spring comnut 15 which.is internally threaded or enpressor employed more especially toaciligagement with an arm 16 shaped angularly tate the removal of motorvalves, and the in crossA section to prevent vrotation Yf the object ofthis invention is to provide a simarm in the frame 4and adapted toextend ,55

It is often found diiicult to withdraw the valve spring from positionafter the valve has been remo-ved and in order that this may be readilydone, I have provided a support 34 as shown lin Figure 5 which isbowlshaped or suitably'rounded for engagementv with the valve seat andwhich is provided with a central hub 35 having an opening 36 therein tovreceive and support,i the spindle for lifting the shoe to compress thevalve spring, 'after'which the shoe portion 2l and the lower end ofthevalve spring may be swung outwardly by rocking the support 34 von thevalve seat due to its curved contour and* they spring removed from theengine by the operation ofthe handle 32 to release the compression ofthe spring.

Inthe event the spindle 29 might become stuck in position, I haveprovided a boss 37 on the upper end of the handle 32'for receiv-y ingth'e'tap of a hammer to dislodge any inf crustation and free the spindlein its bearing 28;

It will be further observed that when the arm 16 is placed in theoutermosty opening l1 of the' frame it will be engaged. by the extendedbearingk leg 38 to support the arm against undue springing of the parts'due to the increased; leverage when thegarm is in this outermostposition.

My improved valve compressing device is rvvery simple in construction.`and yet is effective in its operation andl is so,` designed that itmaybe quickly appliedtoan engine' 'solely towards the constructionillustrated,

butI -desire it to be understood' that I reserve the privilege ofresorting to all the `mechanical changes to which the device issusceptible, the invention being deiined and limitedonly by the terms ofthe appended claims.

I claim: y Y
